Abstract
The utility model provides a bidirectional axial positioning structure of a transmission shaft, which comprises a stop washer, positioning dowels, nuts and the transmission shaft. The stop washer consists of two semi-rings, the positioning dowels and the nuts are used for fixing the two semi-rings, a positioning groove is arranged on the periphery of the transmission shaft, and the stop washer is embedded in the positioning groove of the transmission shaft and fastened with the nuts through the positioning dowels. The bidirectional axial positioning structure can be arranged at any position of the transmission shaft, and the structure of the transmission shaft is flexibly designed and unrestricted, so that the integral structure is more compact. The bidirectional axial positioning structure of the transmission shaft is particularly applicable to a mechanical transmission system which is compact in structure and can not utilize plummers close to two ends of the transmission shaft to limit.
Description
[technical field]
The utility model relates to mechanical field, and particularly a kind of transmission shaft needs the mechanical transmission structure of axially locating.
[background technique]
Conventional transmission shaft location is to utilize stepped drive shaft self shaft shoulder spacing at the frame two ends, and transmission shaft structure receives certain limitation like this.
[model utility content]
The purpose of the utility model provides a kind of transmission shaft bi-directional axial position structure, to solve the problems of the technologies described above.
To achieve these goals, the utility model adopts following technological scheme:
A kind of transmission shaft bi-directional axial position structure comprises the lock washer of two semi-rings compositions, positioning dowel, nut and the transmission shaft of fixing two semi-rings; The transmission shaft periphery is provided with locating slot; Also fastening in the locating slot of lock washer embedding transmission shaft through positioning dowel and nut.
The utility model further improves and is: the semi-ring both sides are provided with fastening boss, and fastening boss is provided with the through hole that supplies positioning dowel to pass.
The utility model further improves and is: the through hole interference fit on positioning dowel and the semi-ring.
The utility model further improves and is: two semi-rings are fastening through two positioning dowels and four nuts, and screw lock has two nuts on each positioning dowel.
The utility model further improves and is: the internal diameter of locating slot is less than the internal diameter of lock washer.
Two semi-rings are cut along central axial direction by the lock washer of a complete processing and form, and joint-cutting should be narrow slit, stitches wide less than 0.2mm.Positioning dowel adopts interference fit, passes two through holes on the semi-ring, utilizes four nuts, and two semi-rings is fastening and tighten, and plays preventing loosening effect.When two semi-rings combine to form lock washer, should embed in the locating slot on the transmission shaft, the footpath should be slightly smaller than lock washer and be cut into the diameter of bore of processing before two semi-rings at the bottom of the locating slot on the transmission shaft, and the seam that diameter difference and lock washer cut is wide close.Shallow slot width on the transmission shaft should be slightly larger than the thickness of lock washer.
With respect to existing technology, the utlity model has following advantage: this fixed structure can be arranged on the transmission shaft arbitrary position, and transmission shaft structure flexible design, unrestricted, can make overall structure compact more like this; This mechanism's particularly suitable compact structure, can't utilize near the spacing machine driven system of the shaft shoulder at transmission shaft two ends.
[description of drawings]
Fig. 1 is the schematic representation of the utility model position structure;
Fig. 2 is the sectional view of Fig. 1 along the A-A line;
Fig. 3 is the utility model position structure sectional view;
Fig. 4 is the side view of Fig. 3;
Fig. 5 is the sectional view of Fig. 3 along the B-B line.
[embodiment]
Below in conjunction with accompanying drawing the utility model is further specified.
See also Fig. 1 to shown in Figure 5, the utility model comprise that 2,4 of lock washers that two semi-rings form 1, two positioning dowels are fastening and prevent loose nut 3 and the external diameter that is axially located on the transmission shaft 4 of locating slot 40 is arranged.
Two semi-rings are placed in respectively on the transmission shaft 4, and two positioning dowels 2 are pressed into two through holes on the semi-ring respectively, and are fixed on the transmission shaft two semi-rings and locking with 4 nuts 3.When two semi-rings combine to form lock washer; Should embed in the locating slot 40 on the transmission shaft 4, transmission shaft 4 passes through a plurality of parts on the transmission shaft 4 that are assemblied in of lock washer 1 both sides again through lock washer 1; Its axial float is hampered by the support of both sides, realizes the bi-directional axial location of transmission shaft 4.
The utility model is applicable to the axial limiting structure of any transmission shaft.This structure can be transmitted the tolerance axial force, little, the compact structure of volume.
